NAIL-MACHINE.

EPECIFIGATION forming part of Letters Patent N0. 313,108, dated March 3, 1885,

- tion.

My invention relates to that class of machines for making tacks in which the nailblank is gripped by its edges, the objects being to substitute for the two stationary bed-dies that have usually been placed in machines a single thick die, part of the face of which is scored to receive the blank tack or nail, the other part being beveled away, so as not to interfere with the free delivery of the tack or nail when completed; also, to hold the blank by an upright nipper until gripped by the moving die, and to so arrange the nipper and its connecting parts that it can be adjusted 'for receiving nails of different sizes. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l isaside elevation. Fig. 2 is avcr ,tical longitudinal section of the machine. Fig.

3 is a planned section, and Fig. at is a perspective view of details. Fig. 5 is a plan showing my improved bed-die. Fig. 6 is a side elevation of the same. Fig. 7 is a detail showing the working-face of die F.

In the drawings, A represents the frame of the machine, and D the main shaft, to which the operating-cams are attached.

D, Fig. 1, is a crank-disk, which operates through its crank-pin d the link D which in turn, operating the lever D, imparts motion to the cutting-jaw D The moving knife H, Figs. 2 and 4., is attached to the jaw D while the stationary knife H is affixed to the frame of the machine.

E, Figs. 1 and 3, is a lever-frame which operates the header All the parts above referred to are old, being elements of the wellknown Reed machine, patented to Jesse Reed, August 14, 1811.

I will now describe the parts thatI considcr new.

bed'die, and the other the back piece, the beddie being provided with a groove in which the blank is held in the process of heading, and the back piece being provided with an angular groove on the same line as the groove in the bed-die, the only use of the back piece being to hold the blank after it is cut off until the gripping and heading devices have time to operate.

In my invention I dispense with the back piece altogether and substitute for it and the bed-die one thick die, F, made in plan, as shown at Fig. 5, and in elevation, as shown at Fig. 6, the end being beveled, as indicated at F F, Fig. 5, and grooved, as shown atF, Fig. 6, the groove F extending from F to F of Fig. 5-that is, about the length of the nailblank that is being worked. The nipper L*, Fig. 4, seizes the nail at right angles and presses it against the bed-die F, Fig. 5, the nipper acting on the blank at a point near F leaving room for the moving die 0, Fig. 4, to come forward and hold the blank firmly against the bed-die F until the nail is headed. The nipper L Figs. 1, 2, and 4, is supported by a basepiece, L, said base-piece L being adj ustable by the screw L, Fig. 2. The nipper L is made of thin metal, so that it may bend and adapt itself to the adj ustmcnt of the screw L. Thus the angle between the upper end of the nipper L and the bed-die F can be varied so as to hold the blank in the best possible position. This nipper L is operated by a spring-lever, L Fig. 4, a projecting arm, L, of which comes in contact with the upper end of L".

L is a link which connects the spring L with the cam-lever L Fig. 4, the cam-lever L being operated by a cam on the main shaft D. (Not shown.)

I am aware of Patent to Haddock, N0. 17 2,427 and therefore lay no claim to the construction therein shown and described.

I claim 1. The combination, with the moving die 0 and beddie F, of the nipper L its adjustable base-piece, spring-lever L link L, and cam-lever L substantially as and for the purpose herein described.

2. In a machine for making edge-gripped nails, the combination of a vertical nippeig with a groove in its working-face for holding its adjustable base-piece, and moving die 0 the blank, and having aportion of its face bevwith a singleithick die adapted to take the eled, substantially as described.
